A 19-year-old Tonganoxie man who suffered brain damage during a dental procedure in Lawrence has filed a lawsuit seeking damages.

The lawsuit alleges that oxygen and nitrous oxide lines were crossed during design and construction of Dr. Kirk Vincent’s office at 4811 Bob Billings Parkway. It also alleges the city, during inspections of the office, should have caught the problem.

The suit was filed in Douglas County District Court on behalf of Austin Stone and seeks compensation from:

• Lawrence oral surgeon Kirk Vincent.

• Action Plumbing of Lawrence, which installed the medical gas lines.

• Patterson Dental Supply Inc., Topeka.

• Blanchard Design Group LLC, Lawrence, the architect on the project.

• Design Build Collaborative LLC, Lawrence, the general contractor on the project.

Stone visited Vincent’s office to have four wisdom teeth removed on March 30, 2009.

The lawsuit alleges that:

During that visit, Vincent tried to sedate Stone with what he believed was a nitrous oxide-oxygen mixture. But Stone didn’t become sedated. The doctor administered Fentanyl and Diazepam, and then Propofol.

At that point, Stone’s heart rate decreased, and Vincent administered what he thought was 100 percent oxygen. In fact, it was pure nitrous oxide.

Stone eventually stopped breathing, and emergency medical workers were called. At Lawrence Memorial Hospital, Stone was diagnosed with brain damage because of oxygen deprivation.

The lawsuit seeks damages for medical expenses, upcoming medical care, as well as expenses that his guardians, Tara Passmore and Lance Stone, have and will incur.

While the lawsuit seeks damages in excess of $75,000 in each of the 12 counts, no exact amount of damages is outlined in the suit.
